I think you haven't missed any of them. That said, you need to do this in patch [1/2], or the kernel between patches [1/2] and [2/2] may be broken on some systems. If you want to do that in separate patches, the current [2/2] should be [1/2] and vice versa.

No, definition of CPUFREQ_SKIP_INITIAL_FREQ_CHECK would be missing then after the first patch.. Anyway, I have fixed that and resent them now..
